4 IMPROVEMENT IN sHUTTE'R-FASTENINGS.

` H0-Qu The Schedule referred ta in these Letters Patent and making part of the same.

To all whom 'it may conce/m Beit known that I, GEORGE V7. OURAM, ofthe city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Fastenings for Shutters, Doors, Sac.; and I do hereby declare that the following'- is a full, clear, and

exact description of' the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is a front view of my improvement in fastenings.`

Figure 2Y is a sectional view through .4k-B.

Figure 3 is aside view of my invention, with the application of'a thumb-screw and bolt.

The' nature of my invention consists in constructing fasteniugs forshutters, doors, Sac., as hereinafter described, so as to combine security and stiffness with freedom of movement, and, at the same time, to prevent clogging by ice or snow.v

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

Thecases O and C', figs. 1 and 3, are madewith raised guides, the sides of which are slightly inclined.

Fitted, and working in the raised guides, is abolt, B, 'the centre of which is made thicker, in order to give it additional strength at this point.

In the centreof the bolt B, iig. 1, is cast or formed a lug, L, for the purpose of operating the same, and on the bolt B, g. 3, is cast or formed a boss, S, the centre of which is bored out, and athread cut therein.

In the opening of the boss S is inserted a rod, R,

the end of which is provided with a thread, and the opposite end flattened out, to serve as athurnb-screw.

In arranging the fastening, as shown in lig. 3, the bolt is placed nearthe bottom ofthe shutter, and immediately opposite to the lower part of the window-sash. An opening is then made through the sash, so that when the bolt is pushed all the way up in C', the opening in the bossS will come directly opposite to the Yopening in the sash. The screw-end of the rod It is then inserted, through the opening in the sash, into the opening in the boss S, and screwed up tight, thus holding the bolt B rmly in place, and preventing it from being pushed back from the outside ofthe shutter.

It will be obvios that, -by inclinin'g the sides ofthe guides of the cases, all snow and rain are turned on, and prevented from accumulating around the bolt; also,

by forming the bolt thicker at the centre,land bringing that part at the point where the greatest strain is on the bolt, I thus prevent all bending or twisting.

Having thus described the construction and operation of mylinvention,

What I claim, and desire to secure by Letters Patent, is

The combination and arrangement of the cases C and C', bolt B, boss S,aud rod R, 'so as to' operate substantially in the manner and for the purpose specified.

In testimony whereof, I have hereunto signed my name, in the presence of two subscribing witnesses.

GEORGE W. OURAM.
